摘　　要：根据空间太阳望远镜成像调焦的要求,设计了一成像镜调焦机构.给出了设计的基本原理及设计方法,即步进电机驱动滚珠丝杠,丝杠通过连接杆和转向关节带动内筒.并根据设计加工制作了实物缩尺模型,进行了误差分析.最后给出了机构在锁定状态,16g重力加速度作用下的力学分析.Based on the requirements of adjustment mechanisms of a space solar telescope's foci, a scheme of the mechanism is proposed. The design principle is illustrated in the article. The movement of the image lens is controlled by the step motor and screw. A model is made according to the design method proposed. The error analysis of the mechanism is also proposed. The structural analysis of the mechanism under launch environment is given.
